Absolute Zero

A ray of light devoid of all warmth lances toward a creature within range, encasing it in a lattice of fine, airless ice.

Make a ranged spell attack against a creature within range. On a hit, the target must make a constitution saving throw. On a failed save, the target takes 6d10 cold damage and becomes paralyzed until it takes any damage or until the start of your next turn.

At the end of each of its turns, the paralyzed target can make another Constitution saving throw, ending the condition on a success.

When the paralysis ends, the target takes 2d10 cold damage.

On a successful saving throw, the target takes half as much damage and isn’t paralyzed.
